MP20043 300mA Linear Regulator Datasheet

Features: MP20043
Dual Channel, 300mA Linear Regul ator With Programmable Output Voltage a nd Output Discharge
DESCRIPTION
The MP 20043 is a dual-channel, low noise, low dropout and high PSRR linear regulator with programmable output voltage. The output voltage of MP20043 ranges from 1 .2V to 3.3V in 100mV increments and 2.5 % accuracy by operating from a +2.5V to +5.5V input. The different output volt age options can be programmed by settin g the voltage of P1 and P2 to VDD, GND or floating. There are 9 different volt age settings in one chip. Each output c hannel can supply up to 300mA of load c urrent. The MP20043 uses two internal P MOSs as the pass devices, which consume s 150μA supply current when both chann els are enabled at no load condition. T he EN1 and EN2 pins control each output respectively. When both channels shutd own simultaneously, the chip turns off and consumes nearly zero operation curr ent which is suitable for battery-power devices. The MP20043 also features current limiting and over te.

MP20043

Dual Channel, 300mA Linear

Regulator With Programmable

Output Voltage and Output Discharge

DESCRIPTION

The MP20043 is a dual-channel, low noise, low

dropout and high PSRR linear regulator with

programmable output voltage. The output

voltage of MP20043 ranges from 1.2V to 3.3V

in 100mV increments and 2.5% accuracy by

operating from a +2.5V to +5.5V input. The

different output voltage options can be

programmed by setting the voltage of P1 and

P2 to VDD, GND or floating. There are 9

different voltage settings in one chip. Each

output channel can supply up to 300mA of load

current.

The MP20043 uses two internal PMOSs as the

pass devices, which consumes 150μA supply

current when both channels are enabled at no

load condition. The EN1 and EN2 pins control

each output respectively. When both channels

shutdown simultaneously, the chip turns off and

consumes nearly zero operation current which

is suitable for battery-power devices. The

MP20043 also features current limiting and over

temperature protection.

It is available in a TQFN8 (2mm×2mm) package
